  1. Aspen and mixed upland forest species

  2. big-leaved asterAster macrophyllus • Large variability in leaf size • Either big single leaf or aster flower • Rough surface • White hairs on stem

  3. trembling aspenPopulus tremuloides • Trembling caused by flattened petioles • Leaves as long as they are wide • Bud is shiny, brown colored

  4. wild strawberryFragaria spp. • Low growing (stolons bright red) • 3 leaflets • On terminal leaflet, teeth of apex on same plane

  5. eastern white pinePinus strobus • 5 (soft) needles per fascicle bundle • Cones big, cylindrical, elongate • Scales are loose and rounded

  6. woodbineParthenocissus inserta • Palmately compound (usually 5) • Leaflets have deep toothed margins • Leaflets coarse • Stems have reddish colorations • Vine

  7. pin cherryPrunus pensylvanica • Smaller twig, usually red colored • Leaf is slender • Red glands (tiny) on margin of teeth • Cluster of fruit all rise from single point (pseudo-umbel)

  8. choke cherryPrunus virginiana • Branches grey/tan • Leaves are oval/elliptical, widest on the last 2/3 of the length • Fruit forms a raceme (central stalk with side pedicels)

  9. green ashFraxinus pennsylvanica • “Canoe paddle” samaras in large clusters • Buds dark brown • Leaf compound, opposite, with terminal leaf • Reduced petioles

  10. balsam firAbies balsamea • Resin blisters common on trunk (pitch-pockets) • Terminal buds • Needles grow on horizontal plane when in the shade • Flattened needles • Stomata appears as white line underneath

  11. white sprucePicea glauca • Needles terrete (4-sided) • Upward scales on trunk • Cones hang down off branch

  12. wild columbineAquilegia canadensis • 3 distinct leaflets • Flower yellow/pink/red • Or a single plant from rhizome

  13. frost grapeVitis riparia

  14. bigtooth aspenPopulus grandidentata • Large serrations • Buds fuzzy, brown, stick out from branch

  15. beaked hazelCorylus cornuta • Leaf sharp, doubly serrate • Understory species • Small catkins • Very distinct fruit

  16. wild sarsaparillaAralia nudicaulis • “Parachute plant” • A forbe • Long petiole grows from rhizome, branches in 3

  17. gray dogwoodCornus racemosa • There is only one specimen located in the cage behind the dining room • Opposite, entire margins • “Arcuate” venation • If leaf is pulled apart, “cottony” veins connect 2 pieces • Buckskin tan color on current growth • Remaining stem is ashy gray
